Myelination, the process by which glial cells ensheath the axons of neurons in layers of myelin, ensures the rapid conduction of electrical impulses in the nervous system. The formation of myelin sheaths is one of the most spectacular examples of cell-cell interaction and coordination in nature.
If we talk about unmyelinated neuron, this means the axon is not covered by this myelin sheath. This then means that the conduction of nerve impulse is slower. To further understand myelin sheath, myelin is considered an electrical insulator. Its purpose is to speed the transmission of nerve impulse.
